The Bocci 28 series is a result of a glass blowing technique developed by Omer Arbel whereby air pressure is intermittently introduced into and then removed from an heated and then rapidly cooled glass matrix. The result is a distorted spherical shape with a composed collection of inner shapes, one of which is made of opaque milk glass and houses a low voltage 20watt xenon bulb. Each pendant is unique in composition, diameter and sometimes shape. They can also be customized in a variety of glass color options. The Bocci 28.5 Random can be used as a single fixture or grouped to create dynamic clusters.
